If your child gets a cavity, a dental filling effectively repairs it. We remove the small area of decay and fill the tooth with a natural, tooth-colored material that restores its strength. At Dentistry at Millennium Park, we keep the visit gentle, comfortable, and reassuring for kids, right here in Chicago's Loop.
A dental filling repairs a tooth that has a cavity. A cavity is a small area of decay, and if it's left alone, it can grow and start to bother your child. A filling stops that by gently removing the decayed part and replacing it with a strong, tooth-colored material.
For kids, we use tooth-colored (composite) fillings that blend in naturally, so your child's smile looks just as it should. We restore the tooth's shape and strength, and your child can get right back to eating, playing, and smiling.
The earlier we catch a cavity, the smaller and simpler the filling, which is one of the many reasons regular checkups matter. When a cavity does turn up, we treat it gently and make the visit as easy as possible.
Your child may need a filling when:
Note: Many cavities cause no symptoms at first, which is why regular visits are so helpful. These visits help us catch and treat issues while they're still small.
Even on baby teeth, treating a cavity promptly is important. A timely filling:
Relieves or prevents a toothache
Stops the decay from spreading to more of the tooth
Protects baby teeth so they can do their job until they fall out naturally
Helps the adult teeth underneath come in healthy
Keeps your child eating, speaking, and smiling comfortably
Our practice is on the 18th floor at 8 S Michigan Ave, steps from Millennium Park and the heart of the Loop, a convenient, welcoming spot to bring the whole family.
We care for families from across downtown Chicago, including the Loop, River North, South Loop, and West Loop, with convenient access by CTA, Metra at Millennium Station, and nearby parking.
Tooth-colored composite blends right in with your child's smile.
A mercury-free choice many parents prefer.
Restores the tooth's shape and strength.
We remove only the decayed part and preserve healthy tooth.
Most fillings are done in a single, gentle visit.
Your child can return to normal activities right away.
We keep the visit gentle and reassuring from start to finish.
Note: Our comfort menu (noise-canceling headphones, Netflix, blankets, and more) helps kids relax, and we explain each step in a friendly, low-key way so nothing feels scary.
Fillings are basic restorative care, and dental insurance often covers a portion of them for children. We're in-network with most major PPOs and will review your family's specific benefits with you before treatment, so you know what to expect.
To keep things easy, we offer financing through CareCredit and Cherry, and we'll always explain your child's treatment and any costs clearly up front. No surprises.
For most children, no. We gently numb the tooth first so your child stays comfortable during the filling, and we take our time to keep them calm. Many kids are surprised by how easy it is. A little tenderness afterward is normal and usually fades quickly.
We know a cavity can feel like a big deal to a child (and a parent). Our team is patient and upbeat, we move at your child's pace, and we never rush or force anything. If your child's tooth ever needs more than a routine filling, we'll explain the situation honestly and walk you through the best options for their care.

Meet Dr. RanganathanOften, yes. Even though baby teeth eventually fall out, they help your child eat and speak and hold space for adult teeth. An untreated cavity can cause pain or infection and affect the adult tooth underneath, so treating it matters.
For most kids, no. We gently numb the tooth so your child stays comfortable, and we keep the visit calm and positive. Any mild tenderness afterward usually fades within a day or two.
We use tooth-colored (composite) fillings that blend in naturally with your child's smile. They're metal-free and restore the tooth's strength and shape.
Sometimes you can't, early cavities often have no symptoms. Watch for tooth sensitivity, a little ache, or a dark spot, and keep up regular checkups so we can catch cavities while they're small.
Often, yes, at least in part, since fillings are basic restorative care. We're in-network with most major PPOs and will review your benefits with you before treatment.
